I built an interface to my reel-reel for echo and delay using the cgs-
23 board. Makes for a great preamp.
http://modularsynthesis.com/modules/DJB-012/djb012.htmI added a switchable gain to my multimix.
http://modularsynthesis.com/oakley/oakley.htmI added a variable gain to my MOTM-890.
http://modularsynthesis.com/motm/MOTM-890.jpghttp://modularsynthesis.com/motm/MOTM-890_panel.jpgNone of these are stereo but the cgs-23 would probably be the easiest
to do. I like the variable gain the best as it seems to work best
across a number of different external units. I've found that some of
my rack units can take pretty high levels also.
